Ke k'hemik'hale efe e sebelisetsoang Flocculation?

Phalloke ts'ebetso e sebelisoang liindastering tse fapaneng, haholo-holo ho hloekisa metsi le ho hloekisa metsi a litšila, ho kopanya likaroloana tse emisitsoeng le li-colloids hore e be likaroloana tse kholoanyane tsa floc.Sena se nolofatsa ho tlosoa ha tsona ka sedimentation kapa filtration.Lisebelisoa tsa lik'hemik'hale tse sebelisetsoang ho phalla li tsejoa e le li-flocculants.E 'ngoe ea li-flocculants tse tloaelehileng le tse sebelisoang haholo ke polyacrylamide.

Polyacrylamideke polymer synthesized ho tloha acrylamide monomers.E teng ka mefuta e fapaneng, ho kenyelletsa anionic, cationic, le non-ionic, e 'ngoe le e' ngoe e na le lits'ebetso tse ikhethileng.Khetho ea mofuta oa polyacrylamide e itšetlehile ka mofuta oa likaroloana tse ka metsing le sephetho se lakatsehang sa ts'ebetso ea flocculation.

Anionic polyacrylamide e qosoa hampe 'me hangata e sebelisoa ho phekola metsi a litšila a nang le likaroloana tse nang le lisebelisoa tse ntle tse kang letsopa le lintho tse phelang.Ka lehlakoreng le leng, cationic polyacrylamide e na le charger e ntle 'me e sebetsa hantle bakeng sa ho hloekisa metsi ka likaroloana tse nang le lisebelisoa tse mpe joalo ka lintho tse tiileng tse emisitsoeng le seretse.Non-ionic polyacrylamide ha e na tefo 'me e loketse bakeng sa flocculation ea mefuta e mengata ea likaroloana.

Li-flocculants tsa Polyacrylamide li sebetsa ka ho hohela holim'a likaroloana, ho etsa marokho pakeng tsa tsona, le ho theha lihlopha tse kholoanyane.Li-flocs tse hlahisoang li bonolo ho lula kapa ho sefa ka ntle ho metsi.Polyacrylamide e ratoa bakeng sa boima ba eona bo phahameng ba limolek'hule, e ntlafatsang bokhoni ba eona ba ho koala le ho phaphamala.

Ntle le polyacrylamide, lik'hemik'hale tse ling li boetse li sebelisoa bakeng sa flocculation, ho itšetlehile ka litlhoko tse khethehileng tsa mokhoa oa phekolo.Inorganic flocculants, joalo kaAluminium Sulfate(alum) le ferric chloride, hangata li sebelisoa ho hloekisa metsi.Lik'hemik'hale tsena li etsa li-floc tsa tšepe tsa hydroxide ha li kenngoa metsing, li thusa ho tlosoa ha likaroloana tse emisitsoeng.

Alum, haholo-holo, e 'nile ea sebelisoa haholo bakeng sa ho hlakisa metsi ka lilemo tse ngata.Ha e kenngoa metsing, alum e kena hydrolysis, e etsa aluminium hydroxide flocs e tšoarang litšila.Joale li-flocs li ka lula, 'me metsi a hloekisitsoeng a ka arohanngoa le sediment.

Flocculation ke mohato oa bohlokoa mekhoeng ea ho hloekisa metsi, ho netefatsa ho tlosoa ha litšila le ho hlahisa metsi a hloekileng.Khetho ea flocculant e itšetlehile ka lintlha tse kang litšobotsi tsa metsi a lokelang ho phekoloa, mofuta oa likaroloana tse teng, le sephetho se lakatsehang sa phekolo.Polyacrylamide le li-flocculants tse ling li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea ts'ebetso ea metsi le lits'ila tsa metsi a litšila, ho kenya letsoho phanong ea metsi a bolokehileng le a nooang bakeng sa merero e fapaneng.
